5.4 Assembling the pump head
Insert the three insert rings (11) in the pump housing; see
Figure 3.
For easier installation of the diaphragms (10), turn the connect-
ing rod to top dead center, beginning with head I. Tighten the
diaphragms well (10) by hand. Repeat the steps for heads II
and III.
For head II, press the middle diaphragm (10) to bottom dead
center with your thumb.
Place the head plate (2) according to Figure .
Insert the resonating diaphragm support (3) and the two O-
rings (4) into the head plate (2).
Place the resonating diaphragm (5) on the head plate (2)
according to Figure . Make sure that the cut-out in the resonat-
ing diaphragm (5) and the cams in the head plate (2) are posi-
tioned correctly.
Insert the six O-rings (7) and anchor valves (8) in the connect-
ing plate (6) according to Figure .
Figure 5: Head installation
Click the three intermediate plates (9) into the connecting plate
(6).
Place the connecting plate (6) on the head plate (2).
Place the complete head on the pump housing. Make sure that
the head sits properly to ensure the desired transfer direction
(direction of arrow).
Insert the eight head screws (1) in the head plate (2), but
tighten them only slightly for now.
Tighten the four inside head screws (1) in a diagonal sequence
by one rotation each.
Tighten the four outside head screws (1) in a diagonal se-
quence by one rotation each.
Repeat steps 12. and 13. until all the head screws (1) are
tightened to 3.5 Nm. This procedure is important to ensure that
the diaphragm is compressed equally, and the pump is leak-
tight.
